Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445606, here are decompositions:

19 + 31445587 = 31445606
67 + 31445539 = 31445606
163 + 31445443 = 31445606
337 + 31445269 = 31445606
373 + 31445233 = 31445606
433 + 31445173 = 31445606
499 + 31445107 = 31445606
613 + 31444993 = 31445606

Showing the first eight; more decompositions exist.
